Just checked for you, all the threads are good and positive and the tapers are in good shape. any damage is cosmetic as shown in the photos, so still plenty of life left in these. I will PM you my details.
Don't mean to be digging up a months-old thread, but are the m569 cranks still available, or have they gone to dyna-ti? If you've still got them, would you consider posting them to Australia?
